View Full Version : Normals ?
Hello, I've got a question : What are Normals and how are they calculated ? I am a beginner in OpenGL and would be glad to get help from you.
Read some of the previous posts on this board...
Normals are vectors. Generally with face normals you can tell which polygons are front-facing you, and vertex normals have something to do with shading.
